The singer and all-around queen, who is pregnant with twins, posted new Instagram photos of her showcasing her baby bump in an off-the-shoulder indigo gown.

Some of the pictures were presented in a slideshow set to the The Isley Brothers’ 1972 song titled, appropriately enough, “Pop That Thang.” Jay Z also makes an appearance alongside Beyoncé in one black and white image, while their 5-year-old daughter Blue Ivy hugs her mom –and twin siblings! — in another photo.
